Cassava (Manihot esculenta Crantz): a global scientific footprint—production, trade, and bibliometric insights

Abstract

Abstract Cassava (Manihot esculenta Crantz) is a vital crop for over 500 million people worldwide, particularly in developing countries, especially Africa. Its role in food security, livelihoods, and various industries has spurred extensive research. This study offers a comprehensive bibliometric analysis of cassava research trends over the past two decades (2000–2023), utilizing data from the Scopus database and exploring the global production and trade outlook for this important crop. Globally, Nigeria's production of 63 million tonnes of cassava in 2021 represented about 20% of the world's total, securing its position as the leading producer. Thailand led cassava exports, reaching a value of $1.29 billion, while China dominated imports with a value of $1.48 billion for cassava products. The study analysis reveals 13,238 publications with 245,020 citations and an h-index of 41, indicating a consistent growth in research output over the past two decades. Brazil emerged as the most prolific contributor, accounting for 13.8% of the publications, followed by Nigeria and China. The study highlights significant disparities in research output and funding between developed and developing nations. Although Nigeria is the world’s leading producer, the research landscape is dominated by developed countries. These findings underscore the need for increased investment and collaborative efforts to enhance research capacity in developing countries, particularly in Africa. By identifying knowledge gaps and fostering global partnerships, we can accelerate progress towards sustainable cassava production and utilisation for the benefit of all.
